Abstract (en)
The invention relates to a system (104) and to a method executed in a vehicle control unit (110), VCU, for controlling wheel slip of a vehicle, wherein the vehicle comprises at least two wheels (102a, 102b) driven by at least primary actuator (106) via an open differential (108). The primary actuator (106) is controlled to rotate at a speed resulting in a slip λ<sub>em</sub> of the primary actuator (106). A signed wheel slip limit λ<sub>lim</sub> is determined by adding a configurable value to the slip λ<sub>em</sub> of the primary actuator, such that λ<sub>lim</sub> > λ<sub>em</sub>. Said at least two wheels (102a, 102b) are controlled to rotate at wheel speeds resulting in respective wheel slips λ<sub>l</sub>, λ<sub>r</sub> below the signed wheel slip limit λ<sub>lim</sub>, wherein each one of λ<sub>l</sub>, λ<sub>r</sub> and λ<sub>em</sub> are signed numerical values.
